Yet another 'critical' Firefox flaw
Summary: Firefox 2.0.0.2 as a high-priority browser
Zalewski, who appears to be running an unofficial MOFFB (month of Firefox bugs) project, released a demo of a memory corruption issue that crashes the browser and puts users at risk of PC takeover attacks.
"Firefox is susceptible to a pretty nasty, and apparently easily exploitable memory corruption vulnerability. When a location transition occurs and the structure of a document is modified from within onUnload event handler, freed memory structures are left in inconsistent state, possibly leading to a remote compromise," Zalewski warned.
Mozilla's security team is tracking the issue.
Zalewski's ongoing browser research has also uncovered a "quite nasty" flaw in Microsoft's Internet Explorer 7.
He described the IE 7 issue as a "combination-type vulnerability" that allows the attacker to:
a) Trap the visitor in a Matrix-esque tarpit webpage that cannot be left by normal means (this is a known brain-damaged design of onUnload Javascript handlers),b) Spoof transitions between pages so that the user thinks he actually managed to leave the affected site, and so that the URL bar displays other addresses we didn't actually go to.
"This opens a plethora of spoofing/phishing scenarios," Zalewski warned. A demonstration page is available for testing purposes.
So far this month, Zalewski's demos have included focus bugs, a location.hostname issue (critical), a blank bug, a bookmark issue and today's unload and trap flaws.

I'm betting on mozilla fixing their product first before microsoft . <NT>
Unlikely.
Thus, it's unlikely you actually have a job, and thus I doubt you have the wherwithal to make a bet.
For those who actually want to discuss the merits of this topic, I apologize. But this response adds, at the very least, the same value to this discussion as the original comment it's targeted at. (i.e. for the interpretive benefit of "intelli"hence, it's no worse than useless.)
Sorry son , I don't do SPAM , like you would have others believe .

I'm with hickum on this ine
"In a world with Windows and Gates, we are no longer stuck behind walls and fences"
The cult of retards...
Get a clue.

I've said it before...
You should try the widgets
I tried them...
It's fine to say.. "People should follow standards" and leave it at that.. But it's another to complain there isn't wide stream adoption when you're trying to play "stubborn" against the world over standards. It's a "GOOD LUCK" race. :)
Treat Websites like ISO Compliance
You would be surprised at how quickly people fall under compliance then.
Although agreed...
That is WHY Opera will stay niche. I'd love to convert, problem is.. It's a sub-standard browser that doesn't support real-world equations.
You can't get 3 billion people to follow a standard, but you sure as hell in a browser can compensate for common weaknesses in standards.
Re: Although agreed...
Convert from Firefox... (NT)
Re: Treat Websites like ISO Compliance
I agree with you *in theory*. Unfortunately, there are plenty of standards-compliant sites that are not rendered correctly even in Opera ? and I say this from experience, as a standards-conscious developer.
hmmm...
Mozilla also taking care of V1.5.0.nn users?
May be fixed
